For years, developers decried the tight fist Sun kept on the development of its office suite, preventing the hacker culture from improving its software. So now that LibreOffice is, well, free, it's not surprising to see one ambitious hacker has developed a mechanism for theming it. Let's have a round of applause for Jan Holesovsky, whose patch in the upcoming 4.0 edition of LibreOffice allows you to style LibreOffice using FireFox Personae. Holesovsky's blog is full of other interesting UI changes made to LibreOffice, proof perhaps that letting hackers hack is the best way to keep your project improving.

Developer clearly stated that he did this project because it seemed to be fun. So either he did this project or didn't do anything for LibreOffice at all. What seems to be better?

BTW it's so very frustrating when other people tell you what you should do with your free time. So, what are you doing for LibreOffice? You don't know programming, you say? Why don't you stop doing whatever crap you're doing now and start learning programming so you could be useful for something finally? And after you learn programming, let me choose you some really important project you'll work in your free time.
